摘　　要：钢筋混凝土结构在遭受火灾后,由于高温的影响,混凝土材料会发生化学变化,强度和延性降低,导致整个结构和构件的物理力学性能降低而产生损伤。根据一栋遭受火灾的住宅工程实例,介绍了火灾后钢筋混凝土结构的检测以及钢筋网复合砂浆加固受火灾结构的加固方案,重点探讨了钢筋网复合砂浆加固该结构梁、板的施工工艺。When reinforced concrete structures suffered in the fire, because of the impact of high temperature, material of concrete will change in chemical, the strength and ductility will decrease, the physical and mechanical properties of the entire structure and components tend to reduce, thereby produce injury. According to a project of residential fire, this article mainly discussed the construction technology of beam and plant with high performance ferrocement. Engineering practice prove that the strengthening method has good effect,and economical construction.
